To aZIZ 'whom t fr/ay concern: l,

Be it known that I, JESSE C. C'Rnwronn, a citizen of the United States, residing at Pittsburgh, Allegheny County, Pennsyl-` vania, have invented a new and useful Improvement in Memoranda Devices, of which the following is a full, clear, and exact description.

The present invention relates generally to memoranda, information or reference devices, and more particularly to devices of this nature assembled in compact form and adapted for pocket and personal use by public speakers, lecturers, teachers, entertainers, etc., or by commuters, advertising promoters and others requiring condensed information or schedules of events.

The principal object of the present invention is to provide a protective casing with a removable and renewable rotatable or changeable indicia carrying-dislror member.

Another object of the invention is to provide in a device of this character an indicia disk or member divided into a plurality of sectors, each having means co-operating with the casing for indicating audibly or frictionallwhen the indicia. is in readingposition.

nother object of the invention is to provide a casing adapted to receive a plurality of independently operable indicia carrying members.

A further object of the invention is to provide means co-operating with the indicia carryingmember for protecting the edge thereof during use.

A still further object of the lnventlon 1s to provide a device of this nature which may be loosely carried Ain the pocket or attached as an ornament to a watch cham or the like.

The `foregoing and other objects,.together with their attendant advantages, will be apparent as the invention becomes better understood by reference to the accompanylng specification and drawings forming a part thereof, it being premised that changes may be made in the various details and the manner of operation. within the scope of the appended claims without departing from the spirit of the invention.

Figure 18 is a sectional view on the line XVIII- XVIII of Figure 17.

Figure 19 is a side view and Figure 20 is a cross-sectional view on the line XX-XX of Figure 19 illustrating a different embodiment of my invention` and Figure 21 is a side view of one of theA Y speaker may deviate at position within the member, but so far as I am aware such devices have never been provided with a readily removable and renewable :disk member, or with means co-operating therewith for indi cating in the manner of the present invention the registry of the respective part-s.

By the use of the present invention, a will from a set course without fear of omitting some important feature, and the strain, produced where subject titles must be memorized, is eliminated. In like manner, it is adapted for use by any one requiring condensed, tabulated or scheduled information of various kinds on widely different subjects.

eferring more particularly to thedrawings, I have illustrated in Figures 1, 2 and 3 one form of my invention as comprising a protective casing 2 of generally circular form ,constructed either of'a base or ornamental metal as may be desired. Portions of the opposite sides of the casing 2 are preferably cut away to provide reading openings 4 for an indicia carrying disk 5 mounted within the casing and provided with a central opening 6 engaging the boss 7 formed on one side of the casing. To permit the ready insertion and withdrawal of the indicia carrying disk for renewing the same or substituting a new disk as may be desired, the casing may be constructed, as shown in Figure 3, so that the edge walls 8 only extend to a position slightly above the center line of the casing. A portion of the sides of the casing may be' pressed inwardly, as shown most clearly in F igure-2, for cooperating with the boss 7 to hold the indicia carrying disk in casing. I may construct the disk 5 of metal, celluloid paper or the like, according to the particular use to which the device is to be placed.

In some cases it may be desirable to use a transparent disk so that light will shine therethrough for advertisingv purposes, or to facilitate reading the indicia thereon. In still other instances the indicia may be applied by the use of luminous paint, and either white or colored backgrounds may be used, the specific arrangement being capable of a variety of different embodiments and uses.

In Figures 4 and 5 I have illustrated a slightly different form of construction in which the casing 2 is provided with a depending finger or projection 9 adapted to cooperate vwith grooves or ribs 10 formed on the indicia carrying member 5a. By reason of this construction it may be readily determined when the disk is in proper alignment with the reading opening.

For protecting the edge of the disk and preventing the same from becoming mutilated, I may in some instances desire to provide the same with a supplemental ring 11 having a projection 11a adapted' to engage a correspondingly shaped depression 12 the formed in the periphery of the. disk 5". With this construction the opposite sides of the casing are preferably held together by means of a bayonet slot connection or the like illustrated as comprising a pocket 14 formed on one of the sides, and a projecting boss 15 formed on the opposite side. The pocket is preferably provided with cam groove openings 16 for the reception of the locking lugs 17 of the opposite member. Due to this construction the sides may be assembled in such manner that the reading openings 41 may be brought either into or out of alignment as may be desired.

In Figures 13 and 14 I ,have illustrated a slightly modified form of the invention disclosed in Figures 1 to 3, and comprising a casing 2b having a reading opening 4b provided with a protecting flange 18. TVith this construction the disk is inserted through the opposite side of the casing, a portion 19 of which may be cut away to facilitate rotation thereof. The disk maybe provided with projections with a correspondingly shaped depression or projection 21 formed in the casing for the purposes already described.

lVhere the size of the device is such that all of the information cannot be contained onone disk, I may provide the device with4 a plurality of disks 22, as indicated in Fig` ures 15 and 16, adapted to be contained within any suitable casing. Each of the disks will necessarily be provided with an opening 24 to permit the reading mattei' contained on the back of the disk co-operating therewith to be read.

-In` Figures 17 and another form of'my invention utilizing a plurality of disks 25 within a' casing 26 having reading openings 27 suitably formed in the opposite sides thereof, and provided with cutaway portions 28 facilitating rotation of the disks. An intermediate partition member 29 may be formed between the si'des of the casing, having a centrally enlarged portion 30 forming bosses co-operating with openings 31 in the disks for frictionally retaining the same in rotatable position within casing. This intermediate partition member is also'preferably provided with a reading opening 291 permitting the reading of the indicia on Vthe backs of the respective disks through the openings 24 formed therein, as described in connection with Figure 16.

The casing 26a of Figures 19 and 20, provided with a reading opening 27 in each side thereof may be provided with depressions 3()a a apted to co-operate with similarly formed recesses 32 in tition member 34 for frictionally retaining the disks 25 in position. It will be understood that with the construction just described, the recesses and projections may be or depressions 20 engaging the central par- 18 there is disclosed of uses for the same.

Certain forms of the invention shown herein are illustrated and claimed in my copending application filed March 11, 1922.

It will b e understood that if desired, the casing may be provided With indicia of suitr able type adapted to cooperate with indicia on the disk, and lthat the indicia 'may be changed at Will according to the use to which the invention is to be placed.

I claim-z l 1. As an article of manufacture, a protective casing, having a reading opening therein and a freelyl rotatable indicia carrying `member removably held therein in reading relation with said reading opening, substantially `as described.
